The shr-test/zoom-image test succeeds with dev-libs/libxml2-2.13.9
but fails with 2.14.2 or later. Apparently HTML parsing in libxml2
has become stricter and now refuses to parse the test case, namely:
<img src="file://.../blank-100x200.png"
i.e. a malformed start tag missing the closing ">" delimiter.
